The paper discusses some factors that differentiate the results of conventional studies on erosion, as well as new research developments with application of software based on simulative mathematical models. A need for the unification of research methods is highlighted, to facilitate the elaboration of more effective systems for anti-erosive management, including choice of suitable anti-erosion crop rotations for use on tilled mountain slopes.
Paper presents a literature review concerning conventional methods of seed quality improvement. There are briefly described the methods of seed vigour improvement through breeding and affecting matemal plants. Post-harvest methods were divided into the following groups: selection of most vigorous seeds, methods of sowing facilitation and precision of seed distribution, seed dressing, methods accelerating germination and improving seedlings vigour.
